fix(doc): fix invalid yaml syntax

[dumbasPL]

yaml values containing : need to be wrapped in quotes

The old example config would crash the app

hi?

[willpower232]

it is supposed to ignore things that have been labelled but apparently it doesn't work 👌

[dumbasPL]

Is there a reason this isn't merged already? Am I missing something?

[willpower232]

The only thing missing is some available time from the actual mantainers who can make commits 😅

This looks good to me, sorry for the delay in merging. I will try to test myself before actually merging but looks like an obvious fix.

I confirm the fix works. Is there anything that prevent the merging ?

By the way, it seems there is another error in the config doc file.
It set a return_path:, but the correct value seems to actually be return_path_domain:.
